Drop MDB (Access) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the result. When one file produces several CSV files they come as a single ZIP.
The MDB to CSV converter is part of this page and runs inside your browser. Your databases are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
MDB opens in a few Microsoft-centric tools and is a legacy format. CSV is plain text that every spreadsheet, database and script can read. MDB is at home in legacy Access databases; CSV is the usual choice for moving tabular data between systems.
One MDB can produce several CSV files (one file per table); when it does, they are offered together as a ZIP download.
Every table is read. Queries, forms, reports and macros are not converted, only the data in the tables.
MDB is the format of Microsoft Access up to Access 2003, built on the Jet database engine. It holds tables, queries, forms and reports in one file. Newer versions of Access use ACCDB, and MDB is mostly opened for migration.
Opens in Microsoft Access, LibreOffice Base and the mdbtools utilities

No. The MDB to CSV conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The values are kept. Anything CSV has no way to express, such as formatting, formulas or nesting, is simplified or left out.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MDB file, press Convert and save the CSV. There is nothing to install.
Yes. Binary data files up to 150 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
